RUFUS BOLDRY, OF CHATSWORTH, ILLINOIS, ASSIGNOR OF ONE-HALF TO JOHN CARNEY, 0F GHATSWORTH, ILLINOIS.

MARKER- FOR CORN-PLANTERS.

T 0 all whom it may concern:

Be it known that I, RUFUS BoLDRY, a citizen of the United States, residing at Chatsworth, in the county of Livingston and State of Illinois, have invented a new and useful Marker for Corn-Planters, of which'the following is a specification.

The invention relates to improvements in devices for raising, lowering and reversing land markers.

The object of the present invention is to improve the construction of devices for raising, lowering and reversing land markers, and to provide a simple and comparatively inexpensive construction of great strength and durability, adapted to be readily applied to an ordinary planter, and capable of convenient operation by the driver to raise and lower the marker to clear a stump or other obstruction, and to reverse the marker from one side of the machine to the other when turning at the end of a row.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a rear elevation of a marker operating device, constructed in accordance with this invention and shown applied to a planter. Fig. 2 is a perspective view of the device and a portion of the frame of the planter. Fig. 3 is a plan view of the same. Fig. 4 is a detail sectional view, taken substantially on the line 4-4 of Fig. 3, the marker bar being in an elevated position. Fig. 5 is a detail sectional view on the line 55 of Fig. 4. Fig. 6 is a detail sectional view on the line 66 of Fig. 1.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the embodiment of the invention illustrated in the accompanying drawings, the marker operating device comprises in its construction a horizontally disposed bearing bracket 1, disposed transversely of the rear end of a planter frame 2, and preferably ar- Specification of Letters Patent.

ranged in the same horizontal plane as the frame, as clearly illustrated in Fig. 2 of the drawings. The bearing bracket is preferably composed of two transverse bars or members 3 and 4, having flat intermediate portions fitted against each other and secured together by rivets 5, or other suitable fastening means, but the bearing bracket may consist of a single casting if desired. The inner portions 6 and 7 of the bars or members of the bracket diverge from the intermediate portions and are spaced apart and provided with alined bearing openings 8 and 9, located centrally of the planter or in the plane of the median line thereof. The inner terminal portion 10 of the bar or member 4 is angularly bent to form an approxi mately L-shaped arm, which is fitted against the inner terminal of the other bar or member 3. The inner portion 6 of the bar or member 3 is bowed rearwardly at 11 to offset its bearing opening from the rear transverse end bar or portion of the frame of the planter, and it is secured to the rear end bar of the planter frame by clips 12 and 13, which embrace the rear end bar of the planter frame. The clip 12 pierces the inner portion 6 of the bar or member 3 and is equipped with nuts, which engage the inner face thereof. The sides of the other clip 13 pierce the inner terminals of both of the bars or members, and its nuts engage the outer face of the bars or members 4. The outer terminals 14 and 15 of the bars or members 3 and 4 project beyond one side of the frame and extend laterally therefrom and are off-set from each other and spaced apart to provide an intervening space or recess 16.

The alined bearing openings 8 and 9 receive a crank pivot 17, secured in the bearings of the spaced inner portions of the bars or members of the bracket 1 by means of a key 18, piercing the pivot and arranged at the inner face of the inner portion 7 of the bar or member 4, as clearly illustrated in Fig. 4 of the drawings, but the pivot may be secured to the bearing bracket in any other desired manner. The crank pivot is provided at its rear end with an arm 19, having an outwardly projecting integral terminal lug 20, secured between spaced ears or flanges 21 of a marker bar 22 by a bolt 23, or other suitable fastening device. The bolt Patented May 16, 1911.

forms a pivotal pintle and with the lug and the ears provide a hinged connection between the marker bar and the pivot to permit the marker bar to swing backward without straining the pivot should it come in contact with an obstruction. The pivot 17 @1- tends longitudinally of the planter, and the marker bar swings transversely of the planter from one side to the other thereof in the usual manner.

The ears or flanges 21 are formed integral with a bar or plate 24, extending along the front face of the inner end of the marker bar and secured to the same by a plurality of bolts 25, or other suitable fastening devices, which pierce the plate or bar 24 and the marker bar. The plate or bar 24 is provided at one side with a laterally projecting approximately V-shaped extension 26, formed integral with the plate or bar and composed of outwardly converging angularly related upper and lower sides. The lower side of the V-shaped extension is provided with a plurality of perforations 27 for the reception of a bolt 23, or other suitable fastening device, which adj ustably connects the inner end of a link 29 with the marker bar. The link 2) is provided at its ends with a plurality of perforations 30, and the bolt 28 is adapted to be arranged in any of the perforations to adjust the link and the marker bar. The link consists of a round rod, and its inner end, which is provided with the perforations 30 is flattened as shown and is adapted to fit against the front face of the V-shaped extension 26.

The outer portion of the link 29 extends through a slot 31 of a flange 32 of an operating lever 33, fulcrumed at an intermediate point in the recess 16 and extending below the bracket 1. The flange 32 is formed integral with an attaching plate or flange 34, which is riveted or otherwise secured to the rear face of the operating lever 33. The flange 32 projects from the rear face of the lever 33 and the slot 31 extends longitudinally thereof. The outer end of the link is provided with a stop 35, adapted to engage the project-ing flange 32 to prevent the link from being withdrawn from the slot 31. The outer stop 35 may consist of a bolt, key, or other suitable fastening device, and a washer is preferably arranged at the inner side of the same, as shown. The link is also equipped with an inner stop 36, located at an intermediate point between the ends of the link and forming a bearing for a coiled spring 37, interposed between the stop 36 and the flange 32. The inner stop is of the same construction as the outer stop, and the coiled spring is adapted to create a pressure on the marker bar for forcing a marker 38 into the ground. The operating lever 33 is pivoted in the slot or recess 16 of the bearing frame by a bolt 39,

or other suitable fastening device, and it is adapted to be oscillated to raise and lower the marker bar and to swing the same from one side of the machine to the other. When the marker bar is lowered and the lever is in the position illustrated in Fig. 1 of the drawings, both the spring and the outer stop are spaced from the projecting flange 32, and the marker. is free to move upwardly and downwardly to conform to the configuration of the ground and to drop into depressions or low places thereof. By moving the lever inwardly from such position, it is carried into contact with the coiled spring 37 and is adapted to place the same under tension to cause the spring to press the marker into the soil. The lever is equipped with a spring actuated dog or detent 40, arranged to engage a toothed segment 41 having supporting arms 42, which are secured to the outer end 14 of the bar or member 3. The dog or detent is controlled by a latch lever mounted on the operating lever and located adjacent to the handle of the outer portion thereof to enable the latch lever and the operating lever to be simultaneously grasped.

The lower depending arm or portion 43 of the operating lever is loosely connected by a link 44, or a plurality of links with the outer end of a coiled spring 45, which is provided at its inner end with an eye 46, which is linked into an eye 47 of a rod 48, located beneath and extending longitudinally of the bearing bracket. The inner terminal portion 49 of the rod 48 is threaded and extends through a depending perforated lug 50 of the angularly bent inner end 10 of the outer bar or member 4, and the said threaded inner portion 49 is equipped with a nut 51 for adjusting the spring.

The downward swinging of the marker bar from the elevated position illustrated in Fig. 2 to the ground at either side of the planter, places the spring 45 under tension, producing a slow downward movement and assisting the operator in both lifting and controlling the marker bar. hen the operating lever is locked in the position illustrated in Fig. 1 of the drawings, the tension of the coiled spring 45 does not affect the free up and down movement of the marker bar, but as soon as the operating lever is released and the spring permitted to act, it will assist the upward movement of the marker. The movement of the operating lever to the right or outwardly fro-m the position shown in Fig. 1, raises the marker until the marker bar assumes practically a perpendicular position, the coiled spring 45 assisting such upward movement. The momentum of the marker bar will carry it beyond the center, and as it descends at the opposite side of the planter the lever moves backwardly or inwardly, and the spring 45 is placed under tension. The locking of the lever not only relieves the marker bar of the tension of the spring 45, but enables pressure to be placed on the marker through the spring 37.
